ANNOUNCEMENTS
The paper industry in India is increasing at a very rapid rate. Paper products are used widely-from education to food and packaging, trade etc. Currently there are about 759 PPIs in India with a production of almost 10 million tonnes per year.
This report has aimed to do a comparative analysis of four pulp and paper mills from the Muzaffarnagar district of U.P India, by collecting the industrial wastewater samples from inlet and outlet of ETP and analyzing the various parameters in order to know the pollution load of these effluents.
The paper also aims to present environmental implications of these industries and the various polluting agents in PPIs, depending on the pulping process followed by the particular industry.
The samples were collected from 3 agro based industries and 1 wood based industry. The effluents were checked for pH, Color, TDS, TSS, DO, BOD, COD etc.
Furthermore, the paper discusses the environmental consequences of the pulp & paper industries in qualitative and quantitative terms. The paper production process emits harmful gases into the air such as nitrogen oxides and sulphur compounds, along with discharging organic compounds into the water bodies harming the ecology.
The study is based primarily on analysis of the samples collected from mills and secondary sources. The major data has been taken from reports of CPCB, CPPRI ranging from financial year 2000-2001 to 2016-17. The collected data has been analyzed and presented in the form of tables, pie charts, graphs and standard norms.
This paper also presents a SWOT analysis of pulp and paper industries identifying the various strengths and weakness within the system of paper manufacturing, and various treatment technologies that would reduce the production load of the effluent. A questionnaire was also framed to know the perception of local residents and how these industries have an impact on the surrounding environment.
